point perforations may e indicated by print- Ying upon a record strip,and, in addition thereto, such printing mechanisms are alsol employedtorepresent the result ofsome'couiputation, such as a total of a series ofitems. It frequently happens that it is desirable to identify theprinted items or computations by printed words, abbreviations or thelike,

and in some instances this can readily be ac,- complished bysubstituting letter type for the numeral bearing type so that the indexpoints will represent alphabetical or other cha-racters. Due to thelimitations in the number of index points in a card column, which isusually ten, a limited number of characters may be printed detractingfrom the-usefulness of such an expedient.

It is then the main object of thepresent invent-ion to extendtheusefulness of such printing mechanisms whereby they may .be

i called up when occasion requires to print either numerals, orsubstantially all of the alphabetical characters and under control of asingle card column.

It is a further object to provide an improved mechani m designed to becontrolled by a single oar column which may print either alphabetical ornumeral characters arranged in groups, which characters are far inexcess of the number of index points Ain a card column.' l

It is a further object of the invention to devise an improved meanswhereby characters in 'certain groups may be selected by perforations ina particular field of the card.

It is a further object of the present invention to devise means` wherebygroup selection and type selection voccur during successive card feedingcycles and by separate analyzing means this delayed action permittingone set of brushes to control group selection during one card cycle andanother set of brushes to select a desired type of the group duringthenext card cycle.

It is still a further object of the present invention to provide amechanism employing a card having index points, each index pointrepresenting a numeral or a pluralit of letters of the alphabet wherebysuch index points will select numerals alphabet for printing, or bmeansof an additional index point may given a differential alphabeticalmeaning.

In carrying out the present invention, the preferred means com rises atype carrying member providedv with) a. pluralityof groups offtype, onegroup for example, meral type, the second, letters of the alphabet andthe last, if so desired, other letters of the alphabet. The numeralgroup `of type are normally presented to the rinting point so that asthe usual card per with the analyzing brushes differentially selected.If a perforation should register with an upper or the type will becontrolling brush the corresponding group of alphabetical characterswill be selected prior to the differential selection of the ty e ascontrolled bythe usual index oint perfporations. In this manner the carcontrolling columns may differentially control a number of type tomakeup, for example, either a er, word, or abbreviation.

These and other incidental objects which will be pointed out hereinafterwill be clear from the following detailed description, 'in which; v

Referring to Fig. 1, drive shaft driven by the tabulating motor T. M.(Fig. 4) carries a box cam 27 the race of which reciprocates a bellcrank lever 28 one endof which is attached by a link 29 to areciprocating cross head 30. A pair of levers 28 is provided to carrythe cross head, the latter carrying a series of clutch pawls 31 adaptedto engage with angular notches 32 formed in slidably mounted plates 33,one being provided for each printing order.

When lever 28 is actuated, the engagement of pawl 31 with notch 32 willcause the movement of plate 33 the latter then initially rising upwardlyto a differentially stopped position. Plate 33 may rise until arrestedby a pawl 34 operated by its associated magnet 35 and engaging in one ofa series of notches 36 in the side edge of plate 33.

The spacing of notches 36 corresponds with the spacing of type bars 37constituting, for example, numeral type bars of group A. It will beclear that as plate 33 rises differentially a rack portion 38 thereofwill roll a pinion 39 counterclockwise over the rack teeth 41 of animpositively held plate 42. Pinion 39 is pivotally carried by the lowerend of a slidably mounted plate 43 which carries at `its upper end theset of numeral type 37 constituting group A. lThe movement of plate 43is, therefore, synchronous with the differential movement of plate 33bringingl the desired type bar 37 in correspondence with a printingplaten 44. The movement of plate 33 is also synchronous with themovement of perforated cards 45 (Fig. 5) through the machine so thatwhen a perforation is encountered by a brush in the tabulator, thecorresponding magnet 35 is energized, as will be hereinafter set forth,and the plates 33 and 43 are stopped at a point in their upwarrd travelwhich brings the type corresponding to such perforation into theprinting position and holds it there until after printing.

The plate 33 may be stopped prior to the time that the cross head 30completes its upward movement in which case pawl 31 merely rides out ofengagement with the related notch 32 permitting an upward independentmovement of the cross head 30. As the cross head is moved reverselydownwardly the pawl 31 will re-enter the notch 32 to positively restorethe plate 33 to its normal position.

Any suitable means may be provided for impelling the selected typeagainst the platen 44 to perform the printing function, and mayconstitute hammers-46 each of which -impels an associated plunger 47against the s electcd type. The hammers are adapted to be struck by abail 48 lhaving suitable connections to the operating parts of themachine. Since the hammer details form no part of the present inventionthey are not shown or described in detail herein and for details of apreferred construction, reference may be had to the application of C. D.Lake, Serial No. 541,347,

filed March 6, 1922.

In the manner just described any of the numerals may be selected forprinting, the particular one selected depending upon the position of theindex point in the card column. It is desirable, at times, to printletters to form words, abbreviations or the like and to this end plate43 carries two other sets of alphabet type, the alphabet group B beingarranged above the numeral group A while the alphabet group C isarranged below the numeral group A. The group of type B are selected forprinting by an index omt in the R position (see Fig. 5) while tiie groupof type C are selected for printing by an index point in the X position.The type in the particular group selected are selected. for printing byth'e usual index points in the card column.

The selection of the groups of t pe B and C in` the present instance iscontro led'by the positioning of the slidably mounted plate 42 chereinbefore mentioned. It will be clear that if plate 42 is moveddownwardly from the position shown in Fig. 1 to Fig. 2 the rack teeth 41will cause pinion 39 to roll over rack teeth 38 in a counterclockwisedirection drawin plate 43 downwardly to present the type o group B ltothe printing platen. Plate 42 1s impositively held in its normalposition by a plunger 49 engaging a notch 50 but when the late 42 ismoved to the position shown in ig. 2 the plunger 49 will engage anotch51 in the side edge of the plate.

The extent that pinion 39 will roll over rack teeth 38 depends upon theupward differential arrested movement of plate 33, as hereinbeforedescribed, so that by a-composite opposite movement of plates 42 and 33plate 43 may be adjusted to any intermediate position to select any typefor printing. From .Fig. 1 it will be observed that an equal andopposite movement of plates 33 and 42 during the time that theperforations are being analyzed will result in no movement of bai' 43but when' a perforation in a card column causes the energization of amagnet 35 the pawl 34 engaging one of the notches 36 (Fig. 2) will stopthe upward movement of plate 33. Plate 42 continues, however, to itslowermost position rolling pinion 39 counterclockwise over rack teeth 38thus drawing plate 43 downwardly to select the third type from the topfor printing. In a similar manner other type of group B may be selectedfor operation.

The preferred means employed to position plate 42 downwardly to selectthe alphabet type of group B comprises a cam slide 53 the lower camsurface of which coacts with a stud 54 carried by plate 42 so that asslide 53 moves to the left its coaction with stud 54 will cause plate 42to.be cammed downwardly to the position shown in Fig. 2. Slide 53 isprovided with rack teeth 54 normally out of engagement but adapted toengage the teeth of a mutilated gear 55 which l carries a clutch pawl 56associated with a sequently driving. slide 53 to the left by the gear 55and against the tension of a restoring spring 63. As slide 53 reachesthe position shown in Fig. 2, a straight edge or dwell 64 coacts withstud 54 during which time printing from the selected type is effected.At the termination of the movement of slide 53 to the left and after theprinting operation pawl 56 (Fig. 2) strikes the end of restored latchinpawl 60'resulting in the disengagement 0%' pawl 56 with notch 58. Spring63 restores the slide 53 to its normal position Fig. l) and independentof gear 55 since t e teeth thereof clear the rack teeth 54 at thetermination of the movement of slide 53.4

Restoration of the slide42to its normal position to cause Vthe numeraltype of group A to again be normally selected isetfected by a cam 65(Fig. 2) attached to a constantly rotating shaft 66 ,since shaft 59(Fig. 1) carries a gear 67 (Fig. 1) meshing with a similar gear 68attached to the shaft 66. The profile of cam 65 coacts with a roller 69(Fig. 2) carl ried by a lever 70, a pair being provided to support across rod 71 adapted to engage u nder projections 72 of the plates 42 torestore them to their upward normal position when said levers are rockedby the cam 65. This restoring action occurs, of course, after theprintlng operations again positlomng the type to normal position forselection in accordance with perforations of a successively fed recordcard.

A similar device is provided for selecting the type bars constitutingfthe lowermost or group C, which are also preferably alphabeticalcharacter bearing type. The C group of type are selected by an indexpoint appearing 1n the so-called X position, which is the eleventh indexpoint position on the card. The desired type in group C selected forprinting is controlled in accordance with the usual index pointsappearing in the same column as the X index point.

A slide 73 coacting with stud 54 is provided for the purpose ofelevating plate 42 to select group C type for operation, since it willbe apparent that as plate 42 risesthe rack teeth 41 will cause pinion 39to roll clockwise over the rack teeth 38 to elevate plate 43 bringingthe type of groulp C in correspondence with the printing p aten 44, (seeFig.

3). This position of plate 43 is impositively held by the pin 49coacting with a notch 74 in plate 42. rIhe supplemental upwarddifferential movement of plate 43 is controlled in the usual manner,that is, by the differential time energization of magnet 35 permittingpawl 34 to engage one of vthe notches 36 as plate 33 is elevated by bellcrank lever 28. f

If plate 33 is arrested, the continued upward movement of plate 42 bythe movement of Aslide 73 to the left will finally adjust plate 43 toselect the desired printing. v

For the purpose of actuating plate'7 3 there is provided a mutilatedgear 7 5V (Fig. 1) whose teeth are adapted to subse uently mesh withrack teeth 76 of slide 73. T e mutilated gear carries the usual clutchpawl 77 adapted to engage a notch 78 in the constantly rotated shaft 66,the effective action of the clutch pawl being established when alatching pawl 79 is operated bythe energization of magnet 80.Magnet'SGis energized when an index point appears in the X position.Slide 73 type of group C for 1s restored to normal by the usual spring81' while a cam 82 (Fig. 2) attached to shaft 59 rocks a pair'of levers83 vto restore each plate 42 to its central normal position. The levers83 carry a cross rod 84 which is positioned over the projections 72 todepress the plates 42 to normal. Restoration of the arts brings them tothe position illustrated) in Fig. 1 where the numeral type of group Amay be normally selected for printing..

The construction and operation of the commutator mechanism forselectively controlling the energization of magnets 62 and 80 will beexplained in connection with Fig. 4 of the drawings. The circuit diagramillustrated in this ligure is similar to that disclosed inthe co-pendinapplication ofG. F. Daly and R. E. Page, rial No. 6,980, filed Feb. 5,1925, the circuits being altered to include the new mechanism to realizethe present advantages.

A card column controlling numeral printing does not contain theperforations X or R, and has only theusual index point perforation fordifferentially selecting a particular numeral type bar of the group A.These perfor-'ations are sensed by the lower brushes 85. The machine.circuits are, as usual, energized from a source of energy indicated at86 connected to line Wires 88 and 89 by a double pole switch 87. As therecord cards are fed through they are first presented 'to upper fedduring a subsequent card cycle to lower 13 Y brushes 85.' Theseperforations I close the through upper counter magnet circuits traced asfollows for one column, from the left side of the line 88, wire 91,contacts 92, counter magnet 93, brush 85, common bar 94, wire 95 to therlght side of contacts T2, T-3, and when .the first card is being listedthrough contacts T-4,

T--5, by wire 96 to binder post 11.

If a tabulating operation is being performed on a card other than thefirst group the currentv instead of passing through T-4 and T-5 willpass through T-2, and T-3, wire 97, brush 98, segments 99,throughcommutator 100, brush 101, wire 96 to binder post 11.

A After the machine has operated a certain amount contacts T-1 close,extending the circuit ]'ust described from binder p'ost 11 and lowercard lever contacts 102 and 103, closed contacts T1, binder post 9,closed contacts P-3gto the other side of the line. The energization ofcounter magnet 93 sets up a `supplementary circuit-as follows: from theleft side of the line 88, .contacts 104, printer magnet 35, common bar105, wire 106 to non-list switch 634 closed when listing is desired.When this switch is closed, during the first card cycle, and with thecommutator circuit 101, 100 and brush 107 closed during the same cardcycle, current would be supplied from binder post 11 to the common bar105 through wire 10C), contacts LP-1 now closed and through switch 634.In this Way printer call magnets are provided with a return path for thecurrent which, as will be understood, is a secondary circuit which hasbeen completed by the energization of the counter magnets from thebrushes and the subsequent closing of contacts 104. i

It will be understood that if no other perforations appear in a cardcolumn aside from the usual perforation in one of the ten designatedpoints the immoral type in group A will be controlled differentially theparticular type selected depending upon the differential time thatprinting magnet 35 is energized.

The upper brushes 90 which search the record cards for perforations atthe X or R positions are energized through cam contacts 110 which closeduring the feeding of cards and open between successive card feedingcycles. Brushes 90 are, of course, electrically connected in somesuitable'manncr to sockets 111 connecting the pairs of magnets 62, 80,and in the present instance this connection is exemplified by thejumperconnections 112 thus electrically ,connecting a brush 90 and oneof a pair of magnets 62 or 80, depending upon the perforation presentedt0 the upper analyzing brush.

The commutator arrangement preferably provided for selectivelycontrolling the energization of magnets 62 or 80 comprises a 'ver 28 iselevating plate 33.

cylindrical body of insulating material 113 rotating synchronously withthe card feeding mechanism so that as an X perforation reaches a brush90 a metal point 114 contacting with a brush 115 will cause theenergization of magnet 62. But when a perforation at the R position ispresented to a brush 90 another point 116 will simultaneously contact abrush 117 to cause the energization of magnet 80. The points 114 and 116are electrically connected to a metal ring 118 against which a brush 119bears. By either of the spots 1.14 or 116 the circuit extends from themagnets 62 or 80, through ring 118, brush 119, wire 120 to the usual camcontacts 121 t0 the other side of the line 89.

If the group controlling perforation should be at the 12th or R positionmagnet 62 will be energized and the energization of the magnet occurswhen point 114 reaches brush v 115 during the first card feeding cycle.This y results in the subsequent engagement of pawl 56 (Eig. 1) with thenotch 58 of the driving shaft 59 so that substantially at the time theanalyzing brushes 85 search the usual index peints durng the second cardfeeding cycle the teeth of gear 55 will engage the teeth 54 of slide 53thereby actuating slide 53 to depress plate 42 during the same time thatle- The latter will be arrested differentially when a particular magnet35 is energized in accordance with the second or t 7pe selectingperforation. As the dwell 64 o slide 53 coacts with the stud 54 printingwill be effected from the selected type of'group B after which slide 53is immediately restored. During thei last part of the second cardfeeding cycle'cam 65 (Fig. 2) rocksA lever 70 and through the medium ofrod^71 plate 42 'is restored to normal.

It will also be observed that since magnet 62 is `momentarily energizedto cause the clutching action between notch 58 and pawl 56 that a flatspring 122 (Fig. 1) is provided to restore latching pawl to-normal priorto the completion of the cardfeeding cycle in which the tripping actionoccurs. Thus the magnet 62 is held in readiness to control type groupselection during the next card feeding cycle.

The action of the parts for selecting the type of group C is similar tothat described heretofore wlth the exception that a perforation at the Xor 11th position willl cause ma et to be energized rendering the upperor R clutch operative. Thus when slide 73 is actuated the type carryingplate 43 will "be elevated to select a particular type of group C forprinting.

A relatively important phase of the invention is that the particularmeans provided for controlling group selection is active during -adifferent card cycle than that in which type selection occurs. Thispermits the upper brushes to be used for performing the a plurality of`groups of type,

`:function of group selection while during the subsequent card cycle thetype to be selected may be-controlled by the lower brushes. It will alsobe observed that a minimum movement ot' the type carrying plate isrequired to select the group of type not normally presented to theprinting platen.
